Hi Ken,

I have just posted seven patches against git head (cygwin 3.1.0-0.5).

[PATCH] Cygwin: console: Revive Win7 compatibility.
[PATCH 1/5] Cygwin: pty: Avoid potential segfault in PTY code when ppid = 1.
[PATCH 2/5] Cygwin: pty: Make GDB work again on pty.
[PATCH 3/5] Cygwin: pty: Unify the charset conversion codes into a function.
[PATCH 4/5] Cygwin: pty: Add charset conversion for console apps in legacy PTY.
[PATCH 5/5] Cygwin: pty: Add missing guard when PTY is in the legacy mode.
[PATCH] Cygwin: console: Make console input work in GDB and strace.

I am sorry to submit patches in a short time since last test release.
